What part of "Commander and Chief" are you misunderstanding?
Also point out why this is illegal? Or where it says this is illegal?
So far you have submitted nothing to prove your point.
Let me leave you with your own words yet again...
"Can the president give the president issues orders to a small unit on the battlefield, is it leagal? Constitutionally speaking, sure." - apdst
Again the rest of your argument is nothing but fallacy and double speak.
